论文摘要
得益于核和天体物理学之间的长期合作，我们对宇宙中元素的起源有很好的了解，除了TI和一些中子捕获元素周围的要素。从附近恒星和银河化学演化模型的观察结果之间的比较，需要一个与核心偏离超新星相关的快速中子捕获过程。 C，N，F和一些次要同位素的产生取决于巨大的恒星的旋转，并且使用ALMA的遥远星系的观察表明宇宙富集迅速。即使使用JWST，也可能很难在非常高的红移处找到非常贫穷的或人口III（和无尘）星系。
Thanks to the long-term collaborations between nuclear and astrophysics, we have good understanding on the origin of elements in the universe, except for the elements around Ti and some neutron-capture elements. From the comparison between observations of nearby stars and Galactic chemical evolution models, a rapid neutron-capture process associated with core-collapse supernovae is required. The production of C, N, F and some minor isotopes depends on the rotation of massive stars, and the observations of distant galaxies with ALMA indicate rapid cosmic enrichment. It might be hard to find very metal-poor or Population III (and dust-free) galaxies at very high redshifts even with JWST.
